service I chose is radiology. Diagnostic Imaging is a specialty of medicine that uses nonionizing and ionizing radiation for diagnosing and intervention of disease. Diagnostic Imaging uses imaging techniques, such as magnetic resonance imaging (MRI), X-ray radiography, computed tomography (CT), nuclear medicine, positron emission tomography (PET) and ultrasound to image inside the human anatomy in to diagnose abnormalities and disease. The meaning of imaging in radiology is to create a picture…

Furthermore, radiation during childhood gives patients a greater chance of developing cancer. “Medical Imaging Exposes People to Too Much Radiation”, states that kids are exposed to radiation, and the radiation has time to settle and develop into cancer which makes children more susceptible to cancer (Brownlee, Wainwright❡17). In a few years, the number of cancers of these children will start to appear, and the number will be excessive unless doctors lower the exposure of radiation to prevent…

By Jonas Wilson, Ing. Med. CT KUB A computerized tomography (CT) scan of the kidneys, ureters and bladder (KUB) is referred to as a CT KUB. The scan is done to obtain images from different angles of the urinary system and surrounding structures, which encompasses an area from the superior poles of the kidneys, descending down to the pubic symphysis. These images are acquired in cross-sections or slices, hence the terminology tomographic. They are then processed through a computer to produce…

The increased use of Magnetic Resonance Imaging (MRI) has contributed to the rising cost of imaging expenses. The availability of technology, the increased demand for patients and doctor, and advanced technology are factors that have contributed to the increase. Hypothesis: The increased use and availability in MRI imaging has increased the cost in MRI imaging procedures by approximately 33 percent from 2011 to 2013. In an attempt to identify the connection between increased use of MRI…

The history of dental radiography began on November 8, 1895 with the discovery of the x-ray by Wilhelm Conrad Roentgen. This tremendous discovery changed the future of medical and dental professions, creating a new era for advances and improvements in the medical and dental field. Many other discoveries followed this monumental innovation, and in the late 1940 (s) MRI were discovered. The founding father of MRI is Raymond Damadian, who received a Nobel Prize in 1952. (Reference #1) During its…

Advancement in Radiation Protection: Non-Lead Apron People are exposed to radiation every day just by being alive on this earth. One receives approximately 3,000 µSv of ubiquitous background radiation a year, which means approximately 8.2 µSv per day (Howerton, Iannucci, 2012). This is known as background radiation and is caused by terrestrial, cosmic, and naturally occurring radon. On the other hand, during radiographic examination some degree of biological damage does occur during exposure,…

MRI is a unique medical practice among other imaging methods because, unlike radiographs for example x-rays and ct scans and even radioisotope studies it does not use ionising radiation to create an image of the body this is good because if it does not use ionising radiation it will not have the effects that the radiation causes to the human body. But instead of using other means such as ultrasound to create an image it uses strong magnets and radio waves to create detailed digital images of the…

CHAPTER ONE 1.0 INTRODUCTION 1.1 Background of the Study Ultrasonography is an excellent modality for examining abdominal structures including the location and dimensions of canine kidneys (Remichi et al., 2014). It involves a non-invasive procedure for examination of kidney diseases (Sampaio and Araujo, 2002) and offers advantages over radiography as there are no side effects of radiation and contrast agents (Nyland et al., 1995). Canine kidneys are located in the retroperitoneal region of the…

Elastography is a medical imaging modality that maps the elastic properties of soft tissue. The focus is whether the tissue is hard or soft and will give diagnostic information about the presence or status of a disease. It is concerned with providing images that are related to the stiffness of the tissue. This paper will discuss about elastography and the different types as well as, the principles and components involved with elastography. Peter R. Hoskins a Caucasian, male from United Kingdom…

created and is further filled by an electron from the higher shell and thus an X-ray is emitted to balance the difference in energy between the two electrons. The detector placed on the energy dispersive spectroscope apparatus measures the number of emitted X-rays and their energies. Energy of the X-ray is characteristics of the element from which X-ray is emitted. A spectrum of the relative counts of the detected X-rays is obtained and evaluated for quantitative determinations of the elements…
